Q1) When you turn on the meter to DCV, does it show anything on the lcd?    Does it show 0.000 or nothing on the lcd?

Q2) Did you try a fresh new battery?

Q3) Can you post clear focused pictures of your pcb? both sides please.

Q4) If you hookup the 177 to a DC power supply, how much current does it draw?

Happened suddenly? Under what conditions? Did you just blow a fuse?

Did you just blow a fuse?

The fuse in Fluke handheld multimeters only protect the current ranges.  A bad fuse is likely not the problem here.
